1Clinical and biochemical indexes from 2019-nCoV infected patients linked to viral loads and lung injury显示文摘The outbreak of the 2019-nCoV infection began in December 2019 in Wuhan,Hubei province,and rapidly spread to many provinces in China as well as other countries.Here we report the epidemiological,clinical,laboratory,and radiological characteristics,as well as potential biomarkers for predicting disease severity in 2019-nCoV-infected patients in Shenzhen,China.All 12 cases of the 2019-nCoV-infected patients developed pneumonia and half of them developed acute respiratory distress syndrome (ARDS).The most common laboratory abnormalities were hypoalbuminemia,lymphopenia,decreased percentage of lymphocytes (LYM) and neutrophils (NEU),elevated C-reactive protein (CRP) and lactate dehydrogenase (LDH),and decreased CD8 count.The viral load of 2019-nCoV detected from patient respiratory tracts was positively linked to lung disease severity.ALB,LYM,LYM (%),LDH,NEU (%),and CRP were highly correlated to the acute lung injury.Age,viral load,lung injury score,and blood biochemistry indexes,albumin (ALB),CRP,LDH,LYM (%),LYM,and NEU (%),may be predictors of disease severity.Moreover,the Angiotensin Ⅱlevel in the plasma sample from 2019-nCoV infected patients was markedly elevated and linearly associated to viral load and lung injury.Our results suggest a number of potential diagnosis biomarkers and angiotensin receptor blocker (ARB) drugs for potential repurposing treatment of 2019-nCoV infection.Yingxia Liu Yang Yang Cong Zhang Fengming Huang Fuxiang Wang Jing Yuan Zhaoqin Wang Jinxiu Li Jianming Li Cheng Feng Zheng Zhang Lifei Wang Ling Peng Li Chen Yuhao Qin Dandan Zhao Shuguang Tan Lu Yin Jun Xu Congzhao Zhou Chengyu Jiang Lei Liu 2020Science China(Life Sciences)2020,63,3:157
2Clinical characteristics of 24 asymptomatic infections with COVID-19 screened among close contacts in Nanjing,China显示文摘Previous studies have showed clinical characteristics of patients with the 2019 novel coronavirus disease(COVID-19)and the evidence of person-to-person transmission.Limited data are available for asymptomatic infections.This study aims to present the clinical characteristics of 24 cases with asymptomatic infection screened from close contacts and to show the transmission potential of asymptomatic COVID-19 virus carriers.Epidemiological investigations were conducted among all close contacts of COVID-19 patients(or suspected patients)in Nanjing,Jiangsu Province,China,from Jan 28 to Feb 9,2020,both in clinic and in community.Asymptomatic carriers were laboratory-confirmed positive for the COVID-19 virus by testing the nucleic acid of the pharyngeal swab samples.Their clinical records,laboratory assessments,and chest CT scans were reviewed.As a result,none of the 24 asymptomatic cases presented any obvious symptoms while nucleic acid screening.Five cases(20.8%)developed symptoms(fever,cough,fatigue,etc.)during hospitalization.Twelve(50.0%)cases showed typical CT images of ground-glass chest and 5(20.8%)presented stripe shadowing in the lungs.The remaining 7(29.2%)cases showed normal CT image and had no symptoms during hospitalization.These 7 cases were younger(median age:14.0 years;P=0.012)than the rest.None of the 24 cases developed severe COVID-19 pneumonia or died.The median communicable period,defined as the interval from the first day of positive nucleic acid tests to the first day of continuous negative tests,was 9.5 days(up to 21 days among the 24 asymptomatic cases).Through epidemiological investigation,we observed a typical asymptomatic transmission to the cohabiting family members,which even caused severe COVID-19 pneumonia.Overall,the asymptomatic carriers identified from close contacts were prone to be mildly ill during hospitalization.However,the communicable period could be up to three weeks and the communicated patients could develop severe illness.These results highlighted the importance of close contact tracing and longitudinally surveillance via virus nucleic acid tests.Further isolation recommendation and continuous nucleic acid tests may also be recommended to the patients discharged.Zhiliang Hu Ci Song Chuanjun Xu Guangfu Jin Yaling Chen Xin Xu Hongxia Ma Wei Chen Yuan Lin Yishan Zheng Jianming Wang Zhibin Hu Yongxiang Yi Hongbing Shen 2020Science China(Life Sciences)2020,63,5:77
3Efficacy and safety of a novel anti-HER2 therapeutic antibody RC48 in patients with HER2-overexpressing,locally advanced or metastatic gastric or gastroesophageal junction cancer:a single-arm phase II study显示文摘Background:Current treatment options for human epidermal growth factor receptor 2(HER2)-overexpressing gastric cancer at third-line have shown limited clinical benefit.Further,there is no specific treatment for HER2 immunohistochemistry(IHC)2+and fluorescence in-situ hybridization-negative patients.Here,we report the efficacy and safety of a novel anti-HER2 antibody RC48 for patients with HER2-overexpressing,advanced gastric or gastroesophageal junction cancer.Methods:Patients with HER2-overexpressing(IHC 2+or 3+),locally advanced or metastatic gastric or gastroesophageal junction cancer who were under at least second-line therapy were eligible and received RC482.5 mg/kg alone every 2 weeks.The primary endpoint was the objective response rate(ORR)assessed by an independent review committee.Secondary endpoints included progressionfree survival(PFS),overall survival(OS),duration of response,time to progression,disease control rate,and safety.Results:Of 179 patients screened,125 were eligible and received RC48 treatment.The ORR was 24.8%(95%confidence interval[CI]:17.5%-33.3%).The median PFS and OS were 4.1 months(95%CI:3.7-4.9 months)and 7.9 months(95%CI:6.7-9.9 months),respectively.The most frequently reported adverse events were decreased white blood cell count(53.6%),asthenia(53.6%),hair loss(53.6%),decreased neutrophil count(52.0%),anemia(49.6%),and increased aspartate aminotransferase level(43.2%).Serious adverse events(SAEs)occurred in 45(36.0%)patients,and RC48-related SAEs were mainly decreased neutrophil count(3.2%).Seven patients had adverse events that led to death were not RC48-related.Conclusions:RC48 showed promising activity with manageable safety,suggesting potential application in patients with HER2-overexpressing,advanced gastric or gastroesophageal junction cancer who have previously received at least two lines of chemotherapy.Zhi Peng Tianshu Liu Jia Wei Airong Wang Yifu He Liuzhong Yang Xizhi Zhang Nanfeng Fan Suxia Luo Zhen Li Kangsheng Gu Jianwei Lu Jianming Xu Qingxia Fan Ruihua Xu Liangming Zhang Enxiao Li Yuping Sun Guohua Yu Chunmei Bai Yong Liu Jiangzheng Zeng Jieer Ying Xinjun Liang Nong Xu Chao Gao Yongqian Shu Dong Ma Guanghai Dai Shengmian Li Ting Deng Yuehong Cui Jianmin Fang Yi Ba Lin Shen 2021Cancer Communications2021,41,11:29
4Efficacy and safety of sorafenib in patients in the Asia-Pacific region with advanced hepatocellular carcinoma: a phase III randomised, double-blind, placebo-controlled trial显示文摘Ann-Lii Cheng Yoon-Koo Kang Zhendong Chen Chao-Jung Tsao Shukui Qin Jun Suk Kim Rongcheng Luo Jifeng Feng Shenglong Ye Tsai-Sheng Yang Jianming Xu Yan Sun Houjie Liang Jiwei Liu Jiejun Wang Won Young Tak Hongming Pan Karin Burock Jessie Zou Dimitris Volio 2009Lancet Oncology2009,,1:23
5Clinical characteristics and response to tyrosine kinase inhibitors of patients with non-small cell lung cancer harboring uncommon epidermal growth factor receptor mutations显示文摘Objective: To investigate the clinical features of patients with non-small cell lung cancer(NSCLC) harboring uncommon epidermal growth factor receptor(EGFR) mutations, and the treatment outcomes of EGFR tyrosine kinase inhibitors(TKIs) in these patients.Methods: We retrospectively analyzed the data of 128 NSCLC patients pathologically diagnosed with uncommon EGFR mutation in the Department of Pathology, National Cancer Center/Cancer Hospital, Chinese Academy of Medical Sciences & Peking Union Medical College and Beijing Hospital from January 2010 to December 2015, including 40 advanced patients who received EGFR-TKI.Results: Among the total 128 patients, 11 patients were non-adenocarcinoma, including squamous carcinoma(3.9%), adenosquamous carcinoma(2.3%), large cell carcinoma(0.8%), and composite neuroendocrine carcinoma(1.6%). Single mutations accounted for 75.0%(96/128), including G719X(29.7%), S768I(18.0%), 20 exon insertion(13.3%), L861Q(12.5%), De novo T790M(0.8%), and T725(0.8%). Thirty-two patients harbored complex mutations. Forty advanced patients received EGFR-TKI, the objective response rate(ORR) was 20.0%,the disease control rate(DCR) was 85.0%, and the progression-free survival(PFS) was 6.4 [95% confidence interval(95% CI), 4.8–7.9] months. The exploratory analysis of tumor response and PFS in 33 patients with G719X/S768I/L861 Q subtypes showed that ORR was 21.2%(7/33), the DCR was 93.9%(31/33), and PFS was 7.6(95% CI, 5.8–9.4) months. Patients with exon 20 insertion mutation and De novo T790 M experienced rapid disease progression with PFS no more than 2.7 months.Conclusions: Uncommon EGFR-mutant NSCLCs are heterogeneous, EGFR-TKIs can have different efficacy in this specific subtype, and thus further individual assessment is required for each case.Yan Zhang Zheng Wang Xuezhi Hao Xingsheng Hu Hongyu Wang Yan Wang Jianming Ying 2017Chinese Journal of Cancer Research2017,29,1:19
6Impact of meteorological conditions on a nine-day particulate matter pollution event observed in December 2013,Shanghai,China显示文摘A severe particulate matter pollution event occurred in Shanghai from 1 to 9 December 2013.The mean hourly mass concentrations of PM_(2.5) and PM_(10) were 211.9 and 249.0 μg/m^3,respectively.Reanalysis data,in situ,and remote-sensing measurements were used to examine the impacts of meteorological conditions on this event.It was found that the synoptic pattern of weak pressure,the reduced planetary boundary layer height,and the passage of two cold fronts were key factors causing the event.Four stages were identified during this event based on the evolution of its PM_(2.5) levels and weather conditions.The highest concentration of PM2.5(602 μg/m^3) was observed in stage 3.High PM2.5 concentrations were closely associated with a low local ventilation index,with an average of 505m^2/s,as well as with the influx of pollutants from upstream,transported by the cold fronts.Jianming Xu Fengxia Yan Ying Xie Fengyun Wang Jianbin Wu Qingyan Fu 2015Particuology2015,13,3:17
7Application of next-generation sequencing technology to precision medicine in cancer: joint consensus of the Tumor Biomarker Committee of the Chinese Society of Clinical Oncology显示文摘Next-generation sequencing(NGS) technology is capable of sequencing millions or billions of DNA molecules simultaneously.Therefore, it represents a promising tool for the analysis of molecular targets for the initial diagnosis of disease, monitoring of disease progression, and identifying the mechanism of drug resistance. On behalf of the Tumor Biomarker Committee of the Chinese Society of Clinical Oncology(CSCO) and the China Actionable Genome Consortium(CAGC), the present expert group hereby proposes advisory guidelines on clinical applications of NGS technology for the analysis of cancer driver genes for precision cancer therapy. This group comprises an assembly of laboratory cancer geneticists, clinical oncologists, bioinformaticians,pathologists, and other professionals. After multiple rounds of discussions and revisions, the expert group has reached a preliminary consensus on the need of NGS in clinical diagnosis, its regulation, and compliance standards in clinical sample collection. Moreover, it has prepared NGS criteria, the sequencing standard operation procedure(SOP), data analysis, report, and NGS platform certification and validation.Xuchao Zhang Zhiyong Liang Shengyue Wang Shun Lu Yong Song Ying Cheng Jianming Ying Weiping Liu Yingyong Hou Yangqiu Li Yi Liu Jun Hou Xiufeng Liu Jianyong Shao Yanhong Tai Zheng Wang Li Fu Hui Li Xiaojun Zhou Hua Bai Mengzhao Wang You Lu Jinji Yang Wenzhao Zhong Qing Zhou Xuening Yang Jie Wang Cheng Huang Xiaoqing Liu Xiaoyan Zhou Shirong Zhang Hongxia Tian Yu Chen Ruibao Ren Ning Liao Chunyan Wu Zhongzheng Zhu Hongming Pan Yanhong Gu Liwei Wang Yunpeng Liu Suzhan Zhang Tianshu Liu Gong Chen Zhimin Shao Binghe Xu Qingyuan Zhang Ruihua Xu Lin Shen Yilong Wu 2019Cancer Biology & Medicine2019,16,1:14
8Menthol-modified casein nanoparticles loading 10-hydroxycamptothecin for glioma targeting therapy显示文摘Chemotherapy outcomes for the treatment of glioma remains unsatisfactory due to the inefficient drug transport across the blood–brain barrier(BBB) and insufficient drug accumulation in the tumor region. Although many approaches, including various nanosystems, have been developed to promote the distribution of chemotherapeutics in the brain tumor, the delivery efficiency and the possible damage to the normal brain function still greatly restrict the clinical application of the nanocarriers.Therefore, it is urgent and necessary to discover more safe and effective BBB penetration and gliomatargeting strategies. In the present study, menthol, one of the strongest BBB penetration enhancers screened from traditional Chinese medicine, was conjugated to casein, a natural food protein with brain targeting capability. Then the conjugate self-assembled into the nanoparticles to load anti-cancer drugs.The nanoparticles were characterized to have appropriate size, spheroid shape and high loading drug capacity. Tumor spheroid penetration experiments demonstrated that penetration ability of mentholmodified casein nanoparticles(M-CA-NP) into the tumor were much deeper than that of unmodified nanoparticles. In vivo imaging further verified that M-CA-NPs exhibited higher brain tumor distribution than unmodified nanoparticles. The median survival time of glioma-bearing mice treated with HCPT-MCA-NPs was significantly prolonged than those treated with free HCPT or HCPT-CA-NPs. HE staining ofthe organs indicated the safety of the nanoparticles. Therefore, the study combined the advantages of traditional Chinese medicine strategy with modern delivery technology for brain targeting, and provide a safe and effective approach for glioma therapy.Caifang Gao Jianming Liang Ying Zhu Chengli Ling Zhekang Cheng Ruixiang Li Jing Qin Weigen Lu Jianxin Wang 2019Acta Pharmaceutica Sinica B2019,9,4:12

10Application of bioactive hydrogels combined with dental pulp stem cells for the repair of large gap peripheral nerve injuries显示文摘Due to the limitations in autogenous nerve grafting or Schwann cell transplantation,large gap peripheral nerve injuries require a bridging strategy supported by nerve conduit.Cell based therapies provide a novel treatment for peripheral nerve injuries.In this study,we first experimented an optimal scaffold material synthesis protocol,from where we selected the 10%GFD formula(10%GelMA hydrogel,recombinant human basic fibroblast growth factor and dental pulp stem cells(DPSCs))to fill a cellulose/soy protein isolate composite membrane(CSM)tube to construct a third generation of nerve regeneration conduit,CSM-GFD.Then this CSM-GFD conduit was applied to repair a 15-mm long defect of sciatic nerve in a rat model.After 12 week post implant surgery,at histologic level,we found CSM-GFD conduit could regenerate nerve tissue like neuron and Schwann like nerve cells and myelinated nerve fibers.At physical level,CSM-GFD achieved functional recovery assessed by a sciatic functional index study.In both levels,CSM-GFD performed like what gold standard,the nerve autograft,could do.Further,we unveiled that almost all newly formed nerve tissue at defect site was originated from the direct differentiation of exogeneous DPSCs in CSM-GFD.In conclusion,we claimed that this third-generation nerve regeneration conduit,CSM-GFD,could be a promising tissue engineering approach to replace the conventional nerve autograft to treat the large gap defect in peripheral nerve injuries.Lihua Luo Yan He Ling Jin Yanni Zhang Fernando P.Guastaldi Abdullkhaleg A.Albashari Fengting Hu Xiaoyan Wang Lei Wang Jian Xiao Lingli Li Jianming Wang Akon Higuchi Qingsong Ye 2021Bioactive Materials2021,6,3:11
11An H3K27me3 demethylase-HSFA2 regulatory loop orchestrates transgenerational thermomemory in Arabidopsis显示文摘Global warming has profound effects on plant growth and fitness.Plants have evolved sophisticated epigenetic machinery to respond quickly to heat,and exhibit transgenerational memory of the heat-induced release of post-transtriptional gene silencing(PTGS).However,how thermomemory is transmitted to progeny and the physiological relevance are elusive.Here we show that heat-induced HEAT SHOCK TRANSCRIPTION FACTOR A2(HSFA2)directly activates the H3K27me3 demethylase RELATIVE OF EARLY FLOWERING 6(REF6),which in turn derepresses HSFA2.REF6 and HSFA2 establish a heritable feedback loop,and activate an E3 ubiquitin ligase,SUPPRESSOR OF GENE SILENCING 3(SGS3)-INTERACTING PROTEIN 1(SGIP1).SGIP1-mediated SGS3 degradation leads to inhibited biosynthesis of trans-acting siRNA(tasiRNA).The REF&HSFA2 loop and reduced tasiRNA converge to release HEAT-INDUCED TAS1 TARGET 5(HTT5),which drives early flowering but attenuates immunity.Thus,heat induces transmitted phe no types via a coordi nated epigenetic network involvi ng histone demethylases,tran scriptio n factors,and tasiRNAs,ensuring reproductive success and transgenerational stress adaptation.Junzhong Liu Lili Feng Xueting Gu Xian Deng Qi Qiu Qun Li Yingying Zhang Muyang Wang Yiwen Deng Ertao Wang Yuke He Isabel Baurle Jianming Li Xiaofeng Cao Zuhua He 2019Cell Research2019,29,5:10
12Abrasive Waterjet Machining Simulation by Coupling Smoothed Particle Hydrodynamics /Finite Element Method显示文摘In dealing with abrasive waterjet machining(AWJM) simulation,most literatures apply finite element method(FEM) to build pure waterjet models or single abrasive particle erosion models.To overcome the mesh distortion caused by large deformation using FEM and to consider the effects of both water and abrasive,the smoothed particle hydrodynamics(SPH) coupled FEM modeling for AWJM simulation is presented,in which the abrasive waterjet is modeled by SPH particles and the target material is modeled by FEM.The two parts interact through contact algorithm.Utilizing this model,abrasive waterjet with high velocity penetrating the target materials is simulated and the mechanism of erosion is depicted.The relationships between the depth of penetration and jet parameters,including water pressure and traverse speed,etc,are analyzed based on the simulation.The simulation results agree well with the existed experimental data.The mixing multi-materials SPH particles,which contain abrasive and water,are adopted by means of the randomized algorithm and material model for the abrasive is presented.The study will not only provide a new powerful tool for the simulation of abrasive waterjet machining,but also be beneficial to understand its cutting mechanism and optimize the operating parameters.WANG Jianming GAO Na GONG Wenjun 2010Chinese Journal of Mechanical Engineering2010,23,5:10
13The bcl-2 mRNA Expression in GCDC-induced Obstructive Jaundice in Rats and Its Implication in Hepatocellular Apoptosi显示文摘The modulatory role of bcl 2 gene in hepatocellular apoptosis of rats with glycochenodeoxycholate (GCDC) induced obstructive jaundice was investigated. The hepatocytes in normal rats and those with bile duct ligation for 7 days, 14 days and 21 days were isolated and obtained by in situ collagenase perfusion and primary culture. The expression of bcl 2 mRNA in the hepatocytes was detected by RT PCR. Primary culture was performed on the hepatocytes from normal rats and those with bile duct ligation for 14 days. 100 μmol/L GCDC was added to the hepatocytes for incubation for 24 h. The hepatocellular apoptotic ratio was measured by using FCM and hepatocellular apoptosis detected in situ by using TUNEL technique. Results showed that the expression of bcl 2 mRNA was not detectable in the hepatocytes of normal rats by RT PCR technique, while detectable in the hepatocytes of those with bile duct ligation (BDL) for 7, 14 and 21 days. Hepatocellular apoptosis in the BDL group was obviously decreased as compared with normal control group after addition of 100 μmol/L GCDC to the cells for 24 h. It was concluded that the hepatocytes in the BDL rats expressed bcl 2. During obstructive jaundice, expression of bcl 2 from the hepatocytes can inhibit the bile salt induced hepatocellular apoptosis.WANG Jianming (王剑明) ZOU Shengquan (邹声泉) 2002Journal of Huazhong University of Science and Technology(Medical Sciences)2002,22,1:10
14Transdifferentiation of tumor infiltrating innate lymphoid cells during progression of colorectal cancer显示文摘Innate lymphoid cells(ILCs)reside in mucosal surfaces to potentiate immune responses,sustain mucosal integrity and maintain tissue homeostasis.However,how tumor infiltrating ILCs modulate tumor development and progression is unclear.Here we profiled tumor infiltrating ILCs during colorectal cancer(CRC)progression by single-cell RNA sequencing.We identified six clusters of tumor infiltrating ILCs with unique features.ILC1s expressed inhibitory receptors and underwent inhibitory functional conversion at the late stage of CRC.ILC2s were classified into three subsets(called ILC2-A,-B,-C),of which ILC2-C subset could facilitate tumor progression.HS3ST1 and PD1 were highly expressed in ILC2s of late stage CRC tumors and deficiency of HS3ST1 or PD1 in ILC2s suppressed tumor growth.Moreover,ILC3s transdifferentiated into ILCregs during CRC progression and ILCregs promoted tumor growth.Of note,TGF-βsignaling initiated the conversion of ILC3s to ILCregs and blockade of TGF-βsignaling could disrupt the ILCreg transdifferentiation and inhibited tumor growth.Thus,intervention of ILC conversions might be a potential strategy for CRC immunotherapy.Shuo Wang Yuan Qu Pengyan Xia Yi Chen Xiaoxiao Zhu Jing Zhang Guan Wang Yong Tian Jianming Ying Zusen Fan 2020Cell Research2020,30,7:9
15Drug targeting through platelet membrane-coated nanoparticles for the treatment of rheumatoid arthritis显示文摘The effective drug treatment of rheumatoid arthritis (RA) is hindered by poordelivery efficiency to the diseased site and the serious side effects caused bywide-spread drug distribution. Traditional drug-targeting strategies, such asligand modification, are complex, laborious, and inefficient. Inspired by theintrinsic relationship between platelets and RA, platelet-mimetic nanoparticles(PNPs) were developed for targeted drug delivery in RA. Through plateletreceptor-mediated adhesion, an intact platelet membrane was coated onto poly(lactic-co-glycolic add) nanopartides, endowing the resulting PNPs with variousfunctional receptors. By coating with platelet membranes, the nanoparticleswere stabilized and had a better circulation profile, providing a benefit forpassive targeting. In vitro binding of PNPs to inflamed endothelium, and in vivoaccumulation in joints of a collagen-induced arthritis (CIA) mouse model of RAwere significantly improved via P-selectin and GVPI recognition, indicating thatthe PNPs could effectively target to RA tissues through multiple mechanisms,similar to natural platelets. Moreover, FK506, a model drug, was loaded into thePNPs and used to treat RA. Pharmacodynamic studies demonstrated that theFK506-PNPs had a notable anti-arthritic effect in CIA mice. This study provides anew biomimetic targeting strategy with great potential for the treatment of RA.Yuwei He Ruixiang Li Jianming Liang Ying Zhu Shuya Zhang Zicong Zheng Jing Qin Zhiqing Pang Jianxin Wang 2018Nano Research2018,11,11:9
16Detection of ALK translocation in non-small cell lung carcinoma(NSCLC) and its clinicopathological significance using the Ventana immunohistochemical staining method: a single-center large-scale investigation of 1,504 Chinese Han patients显示文摘Objective: The novel fully automated immunohistochemistry(IHC) assay-Ventana anaplastic lymphoma kinase(ALK)-D5F3 for screening ALK rearrangements has been approved by China's Food and Drug Administration in 2013, our previous study disclosed a highly specificity and sensitivity nearly 100%, and its efficacy needs to be evaluated in a large cohort of primary lung adenocarcinoma patients, and to compare clinicopathological features with ALK(+) and ALK(-) lung adenocarcinoma.Methods: A total of 1,504 consecutive surgical lung adenocarcinoma cases of Chinese Han population were collected and re-diagnosed according to the 2011 multidisciplinary classification of lung adenocarcinoma.Fully automated Ventana ALK-D5F3 IHC staining with a binary scoring was adopted to evaluate staining and correlated with clinicopathological characters, including age, sex, differentiation degree, histological subtype, lymph node metastasis, and clinical staging.ALK(+) patients were followed-up, and targeted therapy of ALKinhibitors was adopted and observed in patients with stage Ⅳ according to the NCCN guideline.Results: ALK positive adenocarcinomas were identified in 6.6% of the surgically resected 1,504 NSCLCs, and significantly younger than the negative group(P<0.05).Mucinous adenocarcinoma(28.2%) was determined to be predominant in ALK(+) cases, followed by the solid type(11.7%), specific type(6.8%), papillary type(5.6%), acinar type(5.5%), and lepidic type(3.1%), and the differences were statistically significant(χ~2=42.011, P<0.05).ALK(+) adenocarcinoma with lymph node metastasis(10.8%) were significantly higher than that without lymph node metastasis(4.5%)(χ~2=19.809, P<0.05); and ALK(+) in phase Ⅳ(20%) was significantly higher than phase Ⅲ(12.9%), phase Ⅱ(4.2%), phase Ⅰ(4.5%), and phase 0(0)(χ~2=36.068, P<0.05).Multivariate logistic regression disclosed that patient age, AJCC staging, and histological mucinous subtype were correlated with ALK positive staining(OR=0.959, 1.578, 5.036, respectively).Sixty eight patients had followed-up results, five patients out of which primarily diagnosed or progressed into Stage Ⅳ benefited well from targeted therapy with Crizotinib.Conclusions: The ALK fusion protein was seen in 6.6% Chinese NSCLC patients, and mostly seen in younger, clinically higher staging, mucinous and solid predominant adenocarcinoma.Clinical trials in patients of Stage Ⅳ confirmed that ALK-D5F3 Ventana IHC is serviceable in screening ALK-positive candidates for molecular targeted therapy.Lin Yang Yun Ling Lei Guo Di Ma Xuemin Xue Bingning Wang Junling Li Jianming Ying 2016Chinese Journal of Cancer Research2016,28,5:8
17Impending HRT wave precursors to the Wenchuan M_s8.0 earthquake and methods of earthquake impending prediction by using HRT wave显示文摘We deployed four geo-electric monitoring stations in Sichuan and Yunnan provinces from 2004, using the new generation of equipment (PS-100) and technologies to capture the HRT wave earthquake precursor. Before the Wenchuan Ms8.0 earthquake, we recorded the HRT wave precursor at the only operating station in Hongge (HG, Δ=465 km) and found that significant impending signal had been recorded at the station in the early morning ( 0―5 am) of 12th of May, 2008. The precursor for this earthquake is consistent with precursors recorded for other strong earthquakes. The measured physical properties (geo-resistivity and telluric-current) show tidal wave period oscillations from several days to several months before the earthquakes and the amplitude of such HT oscillation increases significantly towards the occurrence of an earthquake. These HT and RT waves from the epicenter have a causal relationship with the earthquakes that happened several days later. The arrival time of two RT waves is proportional to the distance from the station to the epicenter. The estimated natural decay of the amplitude is correlated with the natural period (T0) of the earthquake fault, which is proportional to the fault length. From this relationship, we can predict the earthquake magnitude. For magnitude 6―9 earthquakes, the natural period is about 1―6 hours. Such oscillation comes from the epicenter area and they can propagate several thousand kilometers in the Earth's crust. Before a strong earthquake in the shallow crust, the conductive pore fluid will experience major changes before the fault rapture. Such fluid change will emit an oscillation in the pore fluid pressure. This is the mechanism for the HRT wave generation. Since the China Earthquake Administration funded the HRT wave short-term earth-quake prediction project in 2003, the first record of HRT precursor wave has been recorded from the 2004-12-26 Sumatra Mw9.0 earthquake with the largest epicentre distance Δ=2900 km. Thereafter, we have captured HRT waves from more than twenty strong earthquakes, which are well-matched and show repeatability, consistency and regularity. All our observation with the HRT waves demonstrate that HRT wave precursors to earthquakes indeed exist. Strong earthquakes can be predicted and short-term and impending earthquake prediction is achievable in the very near future. From all the observations, including the ones at HG station from Wenchuan Ms8.0 earthquake, we conclude that using HRT wave to predict earthquakes is feasible.QIAN FuYe ZHAO BiRu QIAN Wei ZHAO Jian HE ShiGen ZHANG HongKui LI ShiYu LI ShaoKun YAN GuLiang WANG ChengMin SUN ZhenKai ZHANG DongNing LU Jun ZHANG Ping YANG GuoJun SUN JiaLin GUO ChunSheng TANG YuXiong XU JianMing XIA KunTao JU Hang YIN BangHong LI Ming YANG DongSheng QI WeiLuo HE TaiMing GUAN HuaPing ZHAO YuLin 2009Science China Earth Sciences2009,52,10:8
18NH3-SCR performance and the resistance to SO2 for Nb doped vanadium based catalyst at low temperatures显示文摘Niobium oxide as the promoter was doped in the V/WTi catalyst for the selective catalytic reduction(SCR)of NO.The results showed that the addition of Nb_2O_5could improve the SCR activity at low temperatures and the 6 wt.%additive was an appropriate dosage.The enhanced reaction activity of adsorbed ammonia species and the improved dispersion of vanadium oxide might be the reasons for the elevation of SCR activity at low temperatures.The resistances to SO_2of 3V6Nb/WTi catalyst at different temperatures were investigated.FTIR spectrum and TG-FTIR result indicated that the deposition of ammonium sulfate species was the main deactivation reason at low temperatures,which still exhibited the reactivity with NO above 200°C on the catalyst surface.There was a synergistic effect among NH_3,H_2O and SO_2that NH_3and H_2O both accelerated the catalyst deactivation in the presence of SO_2at 175°C.The thermal treatment at 400°C could regenerate the deactivated catalyst and get SCR activity recovered.The particle and monolith catalysts both kept stable NO_xconversion at 225°C with high concentration of H_2O and SO_2during the long time tests.Lin Zhu Zhaoping Zhong Jianming Xue Yueyang Xu Chunhua Wang Lixia Wang 2018Journal of Environmental Sciences2018,30,3:8
19Measuring the resilience of an airport network显示文摘Resilience is the ability of a system to withstand and stay operational in the face of an unexpected disturbance or unpredicted changes. Recent studies on air transport system resilience focus on topology characteristics after the disturbance and measure the robustness of the network with respect to connectivity. The dynamic processes occurring at the node and link levels are often ignored. Here we analyze airport network resilience by considering both structural and dynamical aspects. We develop a simulation model to study the operational performance of the air transport system when airports operate at degraded capacity rather than completely shutting down. Our analyses show that the system deteriorates soon after disruptive events occur but returns to an acceptable level after a period of time. Static resilience of the airport network is captured by a phase transition in which a small change to airport capacity will result in a sharp change in system punctuality. After the phase transition point, decreasing airport capacity has little impact on system performance. Critical airports which have significant influence on the performance of whole system are identified, and we find that some of these cannot be detected based on the analysis of network structural indicators alone. Our work shows that air transport system’s resilience can be well understood by combining network science and operational dynamics.Yanjun WANG Jianming ZHAN Xinhua XU Lishuai LI Ping CHEN Mark HANSEN 2019Chinese Journal of Aeronautics2019,32,12:8
20One Stone Four Birds:A Novel Liposomal Delivery System Multi-functionalized with Ginsenoside Rh2 for Tumor Targeting Therapy显示文摘Liposomes hold great potential in anti-cancer drug delivery and the targeting treatment of tumors.However,the clinical therapeutic efficacy of liposomes is still limited by the complexity of tumor microenvironment(TME)and the insufficient accumulation in tumor sites.Meanwhile,the application of cholesterol and polyethylene glycol(PEG),which are usually used to prolong the blood circulation and stabilize the structure of liposomes respectively,has been questioned due to various disadvantages.Herein,we developed a ginsenoside Rh2-based multifunctional liposome system(Rh2-lipo)to effectively address these challenges once for all.Different with the conventional’wooden’liposomes,Rh2-lipo is a much more brilliant carrier with multiple functions.In Rh2-lipo,both cholesterol and PEG were substituted by Rh2,which works as membrane stabilizer,long-circulating stealther,active targeting ligand,and chemotherapy adjuvant at the same time.Firstly,Rh2 could keep the stability of liposomes and avoid the shortcomings caused by cholesterol.Secondly,Rh2-lipo showed a specifically prolonged circulation behavior in the blood.Thirdly,the accumulation of the liposomes in the tumor was significantly enhanced by the interaction of glucose transporter of tumor cells with Rh2.Fourth,Rh2-lipo could remodel the structure and reverse the immunosuppressive environment in TME.When tested in a 4T1 breast carcinoma xenograft model,the paclitaxel-loaded Rh2-lipo realized high efficient tumor growth suppression.Therefore,Rh2-lipo not only innovatively challenges the position of cholesterol as a liposome component,but also provides another innovative potential system with multiple functions for anti-cancer drug delivery.Chao Hong Jianming Liang Jiaxuan Xia Ying Zhu Yizhen Guo Anni Wang Chunyi Lu Hongwei Ren Chen Chen Shiyi Li Dan Wang Huaxing Zhan Jianxin Wang 2020Nano-Micro Letters2020,12,10:8
